BuRGLAR-PROOF SAFE.

SPECIFICATION forming part of Letters Patent No. 470,482, dated March 8,1892.

To all whom it may concern:

Be it known that I, MAX S. GoLDsMITH, a

' citizen of the United States, and a resident of Cincinnati, in thecounty of Hamilton and State of Ohio, have invented certain new anduseful Improvements in Burglar-Proof Safes, of' which the following is aspecification.

My invention particularly relates to burglar-proof safes in which thebody and front closure is circular. lts object is to make a strongclose-littin g burglar-proof safe in which there are no openings fromthe outside to the inside of the safe when closed, and a further objectis to cheapen the construction of this class of safes by avoiding thedrilling and fitting of the hard or drill-proof materialused inburglar-proof safes. These objects -I attain by the means illustrated inthe accompanying drawings, in connection with which the invention willbe irst fully described, and then particularly referred to and pointedout in the claims.

Referring to the drawings, in which like parts are indicatedrby similarreference-letters Wherever they occur throughout the various views,Figurel is a diametrical sectional view of the safe-body in its closedposition. Fig. 2 is a transverse vertical section of the safe-body andbase, taken through line ma: of Fig. l. Fig. 3 isan inside plan View ofthe outer front cap detached from the front closure, With the operatingmechanism for retracting and closing the safe in position. Fig. 4 is aperspective View, on a diminished scale, of the completed safe with thefront closure swung partly around upon its hinges. Fig. 5 is a plan viewof the cap which closes the front of the safe. A

Referring to the parts, A is a chest, which maybe of soft material,either cast or Wrought iron; B, the hard or drill-proof casing inclosingit, and the outer casing O, of either cast or Wrought iron, incasing thedrill-proof body B. These three members form substantially the body ofthe safe, which is mounted upon a cast-metal platform D.

The front cap or closure of the safe is composed of the soft metalflanged cap A', the drill-proof cap B', the outer cap or covering C',the soft-metal ring C2, and the operatiu g and is held by the pins a.

mechanism arranged between the caps O and B by which the front of thesafe is opened or closed.

In `constructing the body of the safe the shell or sheet A, which Iprefer to make of cast-iron, is turned off true upon the outside tosnugly fit Within the drill-proof body B, The forward end of the shell Ais eXteriorly screw-threaded to receive the flanged cap A', which isinteriorly screw-threaded to engage the threads of the shell. The cap Ais rigidly secured in a circular recess in the inner face of the cap Bby screws a', or in any suitable manner. The cap B lits freely withinthe short cylinder or ring C2. The periphery of the cap is turned offtrue, and the inner edge of the ring is bored to receive steelfriction-rollers c,which project slightly beyond the inner rim of thering and serve as anti-friction bearings for the cap B. The ring O2 ishung to the outer shell C upon one side byhinge E, around the pintle ofwhich are arranged ball-bearings e. The opposite side of the shell isprovided. with a pivoted hook c', the hook end of which takes over a pinc2 upon the ring O2 to hold that end of it steady, while the cap orfront closure A B is revolved to unscrew the front and open the safe.The anged edge of the outer cap C is fitted withpins c3, which entercorresponding perforations in the outer edge of the cylinder or ring C2.By this arrangement the cap B and parts rigidly connected with it arearranged to slide away from or toward the body of the safe and the ringO2.

The mechanism by which the front of the safe is opened or closedconsists of an internal toothed ring F, which is secured to the outerface of the cap B by screws passing through it and into said cap and thepinions G and l-I. The periphery of the cogged ring F is grooved, andround-pointed screws f pass through the flange of the cap O into thisgroove, thus furnishing the anti-friction bearings for the ring to turnupon. The cogged gears G are mounted upon'stud-bearings g, passedthrough their hubs and screwed into the inner face of the cap O.V Thepinion I-I is secured upon a shaft h, which passes cenroo trally throughthe cap C. The projecting end of the shaft is angular to receive a crankor lever, by Which the pinion is revolved.

To open the safe from the closed position, (shown in Fig. 1,) the leveror crank is placed upon the shaft h, and the parts A B revolved by thespur; gear until the screws upon the exterior of the chest A and theinterior of the cap A are disengaged. The

hook c is then disengaged from its pin c2, When the front of the safemay be swung around, as shown in Fig. 4.

The opening of the safe is prevented by a dog or bolt upon the cap Aentering a notch a2, cut in the edge of the chest A, said dog or boltbeing controlled by a time-lock in the usual manner.

In order to secure the body of the safe from turning upon its base, aswell as to clamp the outer shell C upon the body B, a ridge o5, Fig. 2,is cast upon the periphery of the shell C, extending from the front edgesome distance back. A slot is cut through this ridge and through theshell and the body B is inserted. The bolts c4 are employed to tightenup the shell upon the body. The base D is recessed upon the top counterto the ridge c5, so that when the safe is placed in position it is notliable to turn upon its base.

Instead of making the cap A in one piece, the flanged portion may bemade as a ring. Pins may be passed through from the inside into the capB', after whichthe center or disk portion rnay be dropped Within thering and secured to the face of the part B', as shown in dotted lines,Fig. I, and the cap A may eX- tend Within the shell A and bescrew-threaded externally to engage interior screw-threads in the shell;but the form shown is the better one.

It will thus be seen that substantially all the iitting required in theconstruction of my safe is performed upon the softer metal and that theparts are readily attached together for use. p

What I claim as new, and desire to secure by Letters Patent, is-

1. In a burglar-proof safe, the combination of the circular drill-proofbody B, the drillproof cap B to close the front end thereof, the chest AWithin the body and having its open end screw-threaded, the flanged capA',

secured to the cap B and having its flange threaded to engage the threadupon the chest, the outer casing for the body B, the ring C2, hinged tosaid outer casing to furnish abearing for the revoluble cap B and itsconnections, the front cap C,1novably connected to the ring C2, thespur-gears G G I-I, mounted upon the inner face of said front cap, andthe internally-oogged ring secured to the cap B substantially as shownand described.

2. The safe-body composed of the inner and outer soft-metal shells andintermediate drillproof shell, the front closure composed of innersoft-metal cap and drill-proof cap B the cylindrical ring C2, hinged tothe outer casing of the body and supporting the front closure and frontcap, the cap O', the pins o3, movably supporting the same and the ringC2, the internally-cogged ring F, secured to the drillproof cap, thespur-gears G G I-I, mounted upon the front cap, the shaft h,- extendingthrough the front cap and having aWrench-seat upon its outer end toreceive a lever by which the gearing is rotated to revolve the caps BA', the said inner shell and cap A being united by screw-threadedconnection, substantially as shown and described.

The combination of the safebody composed of cylindrical shells A B C,the front closure A B', united to the body by screwthreaded connection,the cylindrical ring C2,

the steel .pins c Within said ring to furnish y anti-friction bearingsfor the revoluble closure, the hinge E, connecting the outer shell ltothe body of the ring, the flanged cap C', 1f having pins c3 secured toits edge to slide in `perforations of the' ring C2, the internallycoggedring secured to the front cap B and having its periphery grooved, thescrews f, passing through the [lange of the outer cap C and into thegroove of the cogged ring, the spur-gears G G H, mounted upon the innerface of the front cap, and a shaft h, projecting through the front ofthe cap and having its end formed angular to receive a crank arm orlever for the purpose of revolving the caps A B to open and close thesafe, substantially as shown and described.
